article imageStudy says that 1/3 of breast cancer cases overdiagnosed

By John Louie S. Ramos     Jul 10, 2009 in Health
A new research published at the British Medical Journal (BMJ) suggests that one out of three breast cancer patients were overtreated.
Karsten Jorgensen and Peter Gotzsche the researchers from the Nordic Cochrane Centre in Copenhagen, Denmark extracted data on the prevalence of breast cancer along with other factors such as population size, screening uptake, time periods, and age groups.
The research that took seven years in the making estimated the extent of overdiagnosis in publicly organized mammography screening programmes.
Jorgensen and Gotzsche studied cases of public screenings in the United States, Australia, Britain, Canada, Norway and Sweden.
Hence they concluded that the increase in the breast cancer cases were closely related to the introduction of public screening. Thus, it only proves that one in every three breast cancer patients who undergone public screening is overdiagnosed.
